The most frequently asked questions about Twin Screw pumps.
1. Is the HTS twin screw pump reversible? (Up to what pressure?)
Yes, our HTS twin screw pumps are reversible. The flow direction can be inverted according to operational needs. The maximum pressure depends on the specific model and application characteristics, but generally, these pumps are designed to efficiently handle high pressures, up to 25 bar, depending on the selected configuration.
2. Is the pump self-priming?
HTS twin screw pumps have excellent self-priming capability. However, it is important to consider the application specifics, as efficiency depends on the fluid viscosity and operating conditions.
3. Do HTS twin screw pumps work at low pressures?
HTS pumps are mainly designed for low and medium-pressure applications but still perform well at high pressure, provided the parameters are properly configured. Their ability to maintain a stable and continuous flow makes them ideal even for low-pressure conditions.
4. Is the pump suitable for dosing applications?
Yes, HTS twin screw pumps can also be used in dosing applications. Thanks to their high precision and flow control, they are ideal for processes requiring an exact and consistent fluid distribution, such as in the chemical and food industries.
5. What are the advantages of HTS twin screw pumps compared to other solutions?
HTS twin screw pumps offer numerous advantages, including continuous and constant flow, low pulsations, and greater capacity to handle viscous fluids with suspended solids. They are particularly suitable for applications requiring high performance and reliability, even in challenging working conditions, such as water treatment or industrial environments.
6. How can I choose the right HTS twin screw pump for my application?
The choice of pump depends on various factors, including the type of fluid to be pumped, viscosity, required flow rate, operating pressure, and environmental conditions. Our technical team is available to advise you on the most suitable model for your needs, offering personalized consultations.
7. Are HTS pumps suitable for sludge treatment?
No, HTS twin screw pumps are ideal for highly hygienic sectors, even with high viscosity. Their design allows them to transfer difficult fluids, including those with high solid concentrations, making them ideal for food applications with fruit pieces or solid food parts.
8. Are HTS twin screw pumps suitable for transporting food-grade liquids?
Yes, HTS pumps are suitable for food applications, thanks to their materials and design specifications that ensure hygiene, safety, and product quality. They are designed to meet food safety standards, with easy-to-clean and corrosion-resistant materials.
9. Can the pumps handle high-pressure viscous fluids?
Yes, HTS twin screw pumps are designed to handle highly viscous fluids under high pressure. Their robust structure and twin screw design allow efficient handling of dense and viscous fluids, ensuring a consistent flow even under elevated pressure.
10. Can the pumps suction liquids containing solids or solid particles?
HTS twin screw pumps can suction liquids with suspended solids, making them ideal for industrial applications dealing with fluids containing particles or abrasive solids. Their geometry and design allow them to handle particularly demanding fluids, such as those from chemical and pharmaceutical processes.
11. Can the pumps run dry?
HTS twin screw pumps can run dry for short periods. However, prolonged operation without fluid can damage critical components such as screws and seals. Protection devices such as level sensors and alarms can be integrated to prevent dry-running damage.
12. Can accessories be added to the pumps?
Yes, various accessories can be added to HTS twin screw pumps to improve performance and better adapt to specific application needs. Common accessories include flow, temperature, and pressure sensors, recirculation bypass systems, and other devices to optimize operational efficiency and safety.
13. Are the pumps suitable for ATEX-risk environments?
No, at present, our HTS twin screw pumps are not designed for use in ATEX (Explosive Atmosphere) environments. They are in the process of being certified under the European Directive 2014/34/EU. However, the motors coupled with the pump can be ATEX-certified, ensuring safety in areas where explosive or hazardous atmospheres may be present.
14. How does the pump interact with the products?
HTS twin screw pumps ensure gentle product transfer thanks to their design, which minimizes mechanical stress.
15. What is the shear rate?
The shear rate is very low compared to other pumping technologies, making them ideal for shear-sensitive fluids such as emulsions, creams, solutions with solid particles, or food and cosmetic products.
16. Does the pump work like a centrifugal pump?
No! The product movement is linear, not centrifugal. Unlike centrifugal pumps, which generate flow through centrifugal force, twin screw pumps operate on a volumetric principle, ensuring a constant, pulsation-free flow with greater suction capacity even with viscous fluids.
